Hardline settlers have torched mosques near Ramallah, Jerusalem and Salfit since last Wednesday. The latest string of attacks included a rampage on an army base, sparking condemnation in Israel, and Israeli Prime Minister Benjamin Netanhayu to vow stronger enforcement against lawlessness.

But he rejected a recommendation to classify the Jewish extremists as terrorists, and Israeli lawmakers were set to discuss a law to legalize settlement outposts built on land owned by Palestinians on Sunday.

Extremists amongst Israel's 500,000 strong settler population in the West Bank and Jerusalem reference Israel's measures against outposts in their revenge 'price tag' attacks, usually directed at Palestinians in the West Bank, but recently spilling over into Palestinian sites in Israel and army targets.

Israel distinguishes between state-sanctioned settlement building on occupied Palestinian land and the wildcat outposts, but the international community says all settlements in the West Bank and East Jerusalem break international law.
